Given numbers are 446, 820, 392, 630

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(446, 820) = 182860

GCD(446, 820) = ( 446 x 820 ) / 182860

= 446 / 820

= 446

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

Step3:

LCM(2, 630) = 630

GCD(2, 630) = ( 2 x 630 ) / 630

= 2 / 630

= 2

So, Greatest Common Divisor of 446, 820, 392, 630 is 2
